Sure the over fishing has nothing to do with it.
Last year they wanted the commercials to wipe striped bass off the face of the earth in California to save the salmon. They tried to get this passed because bass were brought there from the east coast.

The Chesapeake commercial guys tried to increase the commercial harvest, with the striped bass are eating all the blue claw crabs can we catch more?Crabs are also over harvested there also,they now get crabs from NY to keep up with the demand.
